1.	A block A of mass 2 kg rests on another block B of mass 8 kg which rests on a horizontal floor . The coefficient of friction between A and B is 0.2 while that between B and floor is 0.5 . When horizontal force F = 25 Nis applied on the block B , the force of friction between A and B is (in N) .
Answer» SOLUTION :As there is no RELATIVE slipping between A and B . as `"" f_(L) = mu N = (5)/(10) XX 100 = 50 N "" [F lt f_(L)]`
